Description
家畜の胚におけるTALENの機能については、インビトロで調製した(IVP)ウシおよびブタの胚を使用して検討した。実施例1および実施例2は、TALEN(left TALENおよびright TALEN)をウシ胚に直接インジェクトして、TALENが特異的に結合した部位に改変を含む遺伝子改変動物を作製したことについて記載する。改変には、ホモ接合型およびヘテロ接合型(両アレル)の改変が含まれた。TALENのmRNAを胚に直接インジェクトしたところ、遺伝子改変の成功が観察された。したがって、TALENを使用した直接的な胚改変は、家畜ゲノム改変の実行可能なアプローチであることが示された。このようにして、周知のプロセスを使用して、動物ファウンダー系統の妊娠および出産のための胚を調製し、代理雌に移植することができる。さらに、その後クローニングまたは他のプロセスに使用するために、レポーターを用いて細胞(たとえば、初代細胞、接合体、卵母細胞、胚盤胞)を選択することも可能である。 The function of TALEN in livestock embryos was examined using (IVP) bovine and porcine embryos prepared in vitro. Examples 1 and 2 describe that TALENs (left TALEN and right TALEN) were directly injected into bovine embryos to produce genetically modified animals containing modifications at the site where TALEN specifically bound. The modifications included homozygous and heterozygous (both alleles) modifications. Successful genetic modification was observed when TALEN mRNA was directly injected into the embryo . Therefore, the direct embryos modified using Talen, was shown to be a viable approach of livestock genome modification. In this way, well-known processes can be used to prepare embryos for animal founder strain pregnancy and delivery and transfer to surrogate females. In addition, cells (eg, primary cells, zygotes, oocytes, blastocysts) can be selected using a reporter for subsequent use in cloning or other processes.
